Mecum's annual Chicago auction, held since 2013 at the Schaumburg Convention Center, always features hundreds of muscle cars, hot rods, resto-mods, and late-model sports and exotics. A 1969 Boss 429 Mustang at $245,000 headlined last year’s auction, which totaled $10.5 million in sales. This year there are cars from eight private collections consigned (including NFL kicker Adam Vinatieri's cars), and the 10 most interesting lots are outlined below.
